Methods in this class are used to handle basic operations on vector layers.
virtual bool saveEdits(QgsVectorLayer *layer) const =0
Should be called, when the features should be commited but the editing session is not ended...
virtual bool startEditing(QgsVectorLayer *layer) const =0
This will be called, whenever a vector layer should be switched to edit mode.
A geometry is the spatial representation of a feature.
Definition: qgsgeometry.h:76
virtual bool stopEditing(QgsVectorLayer *layer, bool allowCancel=true) const =0
Will be called, when an editing session is ended and the features should be commited.
The feature class encapsulates a single feature including its id, geometry and a list of field/values...
Definition: qgsfeature.h:187
virtual bool addFeature(QgsVectorLayer *layer, const QgsAttributeMap &defaultValues=QgsAttributeMap(), const QgsGeometry &defaultGeometry=QgsGeometry(), QgsFeature *feature=nullptr) const =0
This method should/will be called, whenever a new feature will be added to the layer.
Represents a vector layer which manages a vector based data sets.
